Dear Hi, Welcome to HealthcareMagic!
Penis is not a recognized site for acne
(pimples). As per your symptoms, you may have molluscum contagiosum
, warts, ectopic sebaceous glands, to name a few conditions. For timely diagnosis & treatment, my advice is to consult a good dermatologist
in your city.
Wishing you best of health,
Dr NAVEEN KANSAL, MD [PGI, Chd]
